<span> Embryonic stem cell research is kind of a dead area now since there is no way to control the differentiation. Most research is being done on adult stem cells to help map and control the differentiation process.
Stem-cells from aborted fetuses - The government doesn't sponsor this, if it is done it is by private companies not located in the USA. You could try researching umbilical cord stem cells to be somewhere near your topic. They come from the afterbirth of normal deliveries.
You could do a much easier report by covering cloning of mice through stem-cell technology. It is happening and helping scientists understand diseases. </span>
Hypoxia is the state which oxygen is not available in sufficient quantities at a tissue level in the body to maintain the homeostasis. The graph shows the concentration of this condition in Long Island Spund from 91 through 09 in mg/L, showinng in the data that the west area of the region has more cases os hypoxia than the east. Therefore, between the options the one that is a true statement about how well oxygenated to support marine life the region was during that period is the letter C. most years, the water near New York has inadequate oxygen to support marne life.
Answer:
your brain makes special hormones called GnRH, and these hormones signals the testes to make more testosterone.

Answer:
The correct answer is B. Worms move through changes in body structure caused by contraction of muscles compressing their watery fluid.
Explanation:
The hydroskeleton consists of a fluid-filled cavity, surrounded by muscles. The fluid pressure and the action of the muscles that border it, serve to change the body's shape and produce a movement such as digging or swimming. The successive contraction of various metamers, which are provided with bundles of circular and longitudinal muscle fibers, stretching and thickening parts of the body, allow it to move horizontally. Hydrostatic skeletons have a role in the locomotion of annelids, nematodes and other invertebrates. The hydroskeleton has similarities with the hydrostatic muscles.
